Dear Darren
Thank you very much, and I will try to give it a go.
In the event that I can not. You are a life saver if you can help me
out. Everything is in place except this incredibly important item. I
have noticed that you are in Cambridge, maybe we can meet at some point.
I am close by at the mathematics department.
Many many thanks
best regards parham
